The primary function of a regulator is to reduce high-pressure gas in a cylinder or process line to a lower, usable level as it passes from the cylinder to a piece of equipment.

调整器的主要功能是，当钢瓶或过程管道内的高压气体从钢瓶流向设备时，把压力降到较低的可用的水平。

Use a pressure reducing regulator or separate control valve to safely discharge gas from cylinders. Use a check valve to prevent reverse flow into the cylinder.

使用减压调整器或单个的控制阀来安全地从钢瓶中排出气体。采用止回阀，防止回流入钢瓶。

At the end of the shift or work day, close the cylinder valve and bleed the pressure off the regulator and torch equipment.

在下班或工作日结束的时候，关闭钢瓶阀门，放出调整器和吹管设备内的压力。
